Packout Bit Holder - 3/8" Hex

When building my drilling packout kit, I found I had no room for hole saw arbors in the foam used for the saws themselves. I decided to move the arbors and accessories up into a [bin](https://www.thingiverse.com/thing:3712826) that sits above 2" foam. This worked wonderfully.

The ball on the spring arm is a bit large, and the spring arm sits down ever so slightly when printed. I decided that I was satisfied with how it sat, rather than giving up its retention entirely by making it too small to do anything.

Technically, this is using the v6 version that Benjamen made, which can be found [here](https://3dprints.electronsmith.com/milwaukee-tool-style-bit-holders-v6/), rather than the V2 referenced as the remix model.
